直接返すことができます。

以下のパラメータを受け付けます。

* `content` - `str` か `bytes`。
* `status_code` - `int` のHTTPステータスコード。
* `headers` - 文字列の `dict` 。
* `media_type` - メディアタイプを示す `str` 。例えば `"text/html"` 。

FastAPI (実際にはStarlette) は自動的にContent-Lengthヘッダーを含みます。また、media_typeに基づいたContent-Typeヘッダーを含み、テキストタイプのためにcharsetを追加します。

```Python hl_lines="1  18"
{!../../docs_src/response_directly/tutorial002.py!}
```

### `HTMLResponse`

* `status_code` - Um código de status HTTP do tipo `int`.
* `headers` - Um dicionário `dict` de strings.
* `media_type` - Uma `str` informando o media type. E.g. `"text/html"`.

O FastAPI (Starlette, na verdade) irá incluir o cabeçalho Content-Length automaticamente. Ele também irá incluir o cabeçalho Content-Type, baseado no `media_type` e acrescentando uma codificação para tipos textuais.

```Python hl_lines="1  18"

* `status_code` – Ein `int`-HTTP-Statuscode.
* `headers` – Ein `dict` von Strings.
* `media_type` – Ein `str`, der den Medientyp angibt. Z. B. `"text/html"`.

FastAPI (eigentlich Starlette) fügt automatisch einen Content-Length-Header ein. Außerdem wird es einen Content-Type-Header einfügen, der auf dem media_type basiert, und für Texttypen einen Zeichensatz (charset) anfügen.

```Python hl_lines="1  18"

* `content` - A `str` or `bytes`.
* `status_code` - An `int` HTTP status code.
* `headers` - A `dict` of strings.
* `media_type` - A `str` giving the media type. E.g. `"text/html"`.

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the `media_type` and appending a charset for text types.
